Pleased to see this paper now out in @CellReports! Take a look if you're interested in how people use interactive cognitive maps to avoid danger cell.com/cell-reports/fullte…

Interactive cognitive maps support flexible behavior under threat

Wise et al. characterize the computational mechanisms that enable humans to gain reward and avoid danger in the presence of other agents, demonstrating that these abilities rely on the ability to...

In this preprint we refine the method and describe it in detail. Essentially, we train Lasso-regularised regression models to predict sum scores from individual items. The result is a short scale with a set of weights to optimally predict true sum scores. 3/n

⌚ These behaviours seemed fairly stable over time (up to 1 year), and didn't predict change in symptoms, suggesting that they may be a trait-like feature of compulsivity 8/n
